To all whom it may concern: Be it known that I, EDWARD A.. EVERETT, a citizen of the United States, residing at Potsdam, in the countyof- St. Lawrence and State of New York, have invented certain new and useful Improvements in Bottle- Capping Machines, of which the following is a specification. This invention relates to bottle capping machines, with machines for closing by means of aper disks receptacles, usually of cylin rical form, made of paper and used as milk containers.

The object of; this invention is the con struction and arrangement of mechanical parts whereby a disk closure is pressed into the mouth of a paper milk bottle, the edge of the disk being turned up and supplied with adhesive during the ressing operation.

It is also an object of this invention to provide a crate movable independently of the machine itself, but forming an essential part thereof inasmuch as the crate has hollow bottle holders fashioned to receive the bottles and made sufficiently rigid to resist any injurious expansion of the bottles during the capping action of the'machine parts.

To accomplish the objects set forth, the parts are made and associated as illustrated in the accompanying drawings, of which-- Figure 1 represents 'a front view of this parts assembled. Fig, 2 is a top plan view' of the disk closure, and Fig. 3 1s a side view thereof. Fig. 4; is a plan view of the die plate for up-setting the flanges or edges of the disk closures. This view is in part a horizontal section of the tion, and of a relatively arranged at die plate on line w-w'of Fig. 1, and shows the channels for distributing the adhesive to the perforated plates of the various openings through the late. Fig. 5 is a side view of a portion of t e machine, and shows the' stops by, which the. crate is held in proper position for the capping operation. Fig. 6 1s an enlarged view of a presser head in sec- V portion of the die plate in showing the parts about as they are one point during the In this figure are also shown the fabric and perforated plates through which the adhesive reaches the edges. of the closures. The ducts .for the section,

and belongs directly in the class ends to a cross-head frame 8. Presser heads 9 are suitably secured to the lower surface of the cross-head frame. Below the cross-head frame is arranged the die plate 10. There is some interval intentionally left between the presser heads and the die plate, because it is necessary in using this invention that the attendant shall reach all parts of the die plates to place the closures thereon. From the die plate 10 rods 11 extend vertically and pass through guidin sleeves 12 supported by the cross-hea frame as illustrated. The ends of the rods 11 above the cross-head frame are provided with nuts and washers and the springs 13 encircle the ends of the rods between the washers and ,top of the cross-head frame. The die plate is thus cushioned against the cross-headframe asit ping operation.

' As best shown in Fig. 4, the die plate 10 has a number of openings through it. At the top of each opening is a seat 14:! 0011' rises after each capstructedto receive the disk closure. Next; considerin Fig. 6, it will be observed that immediate y below the seat 14 is placed the inwardly-tapering perforated ring '15, covering the channels 16. In Fig. 4 it is shown that the channels 16 lead to and encircle each" opening through the die plate. The lower.

portion of each opening through the die plate is provided with a number of recesses and these recesses are inclined correspondingly with the outwardlytapering lower portion 18 of the openin throu h the die plate. The features just escribe will be further mentioned.

Flexible tubes 19 connect the receptacles 20 with the channels 16 in the die plate, and

the receptacles may hold a quantity of any preferred adhesive, such as selected gum It is desirable shall be wholly arabic and distilled water. that the adhesive employed so lifting impact of the The disk closures 21, as illustrated in Figs.

- 2, 3, and 6, are composed of two layers of veniently and paper, the lower layer being the greaterin diameter. It is the edge of the lower layer of the disk that is turned'up and'sealed in the mouth of the bottle 22 as. hereinafter explained.

A number ,of relatively rigid bottle holders 23 are suitably secured to a crate 24, movable independently of the machine on the table thereof 25, and between the uprights 1 and 2. In Fig. 1 it is set out that the crate fits the interval between the uprights. When moved upon the table and passed'between the uprights the position of the crate is thus fixed so far as its displacement sidewise is concerned. 'It is necessary in addition to conaccurately locate the crate with respect to its,position on the table, in

' rights, the stops/2'6 and 27 may be raised by.

crate is in the proper place order that it may be moved far enough between the uprights but not too far. The parts immediately concerned in thus additionally positioning the crate are best shown in Fig. 5, and comprise the fan-shaped stop plates 26 and 27, both secured to and adapted to be raised by the rock-shaft 28. When the projecting as far as designed in" front and in rear of the upressing the treadle 29 downwardly. But, if the crate is not exactly in its proper place, readily determined after a slight acquaintance with the working of this invention, and projects too far either in front or in rear of the uprights, stops 26 and 27 cannot be raised. In other words, unless the crate is accurately in position to hold the bottles in the necessary attitude with regard to die plate 10, this invention cannot be started, for, the treadle 29 also actuates the beltshifter 30, moving .the power belt 31 from the idle pulley 32, to the fixed pulley 33 thereby driving shaft 3 by means of belt 34.

The remaining elements of this invention may be .most clearly explained in connection with the statement of the mode of operation.

Let it be assumed that the seats 14 of the g9 .d1sk and bottle and permit leakage.

openings through the die plate 10 have each received a attendant, that the crate is in proper position and the mechanism started. In passing over inwardly-tapering perforated plate 15 disk 21 from the-hands of'the more secures the disks in place. After a few minutes, the bottles may be turned up-sidedown and the milk any length of time. As the mechanism starts, the die plate 10 descends and the outwardly-tapering surface 18 engages the upper edge of the bottle and centers the bottle for the action of the presser head 9. The

shoulder 18f at the top of the tapering wall 18, acts as a the opeinng to perm t the entrance of the bottle into the opening a certain distance only. As the disk is forced downwardly the air beneath it escapes by way of ducts 17. The positions and extent of ducts 17 are best shown in Fig. 6, and the escaping air limiting means projecting into will be all retained for flows over the edge of the bottle mto the ducts as indicated by the arrows. .When the capping operation is complete, the foot is taken from treadle29, and-the tendency of the weighted arms 35, loose on shaft 3,

is to resume the positions shown inFig. 1 e

and to raise the sliding plate 36 working in the guides 37, as illustrated in Fig. 1. The slidingplate is secured to the'crosseheadframe 8 as also shown. This movement is permitted by reason of the fact thatthe weights ported the treadle, raise the treadle to its highest position and move the power belt 31 back; to the idle pulley 32. The parts now a come to'rest in "the'positions illustrated in the die plate being raised from the p .and the crate may be removed to t Fig. 1, bottles, give placeto another.
